# Connecting swimming pool heat pump

I am trying to connect a heat pump requiring 30 amps, have 15 amps running to present pool pump.What happens if I connect existing 15 amp line?
If you connect a 30 amp load to a 15 amp circuit, it will blow the fuse or pop the circuit breaker, if there is one. If there isn't, it will likely melt the wire. Look at the rating for the circuit breaker/fuse. The amperage of ALL of the devices connected to that circuit cannot exceed what the breaker/fuse is rated at.

Also, don't just replace the 15 amp breaker or fuse with a 30 amp. The size breaker depends on the size of the wire in the circuit. A 30 amp breaker with a wire gauge for a 15 amp can easily start a fire inside the walls also.

If you don't clearly understand this, you need an electrician.

yeah you can easily Connect their swimming pool with pump.....http://www.aurorapoolsandspas.com/
If the pool you own is a big one and you are yet to purchase a pump for your pool, then you need to mull over your skills and ability to do it yourself before proceeding further. There are various swimming pool supplies that come with instruction, which, if not followed, may procure poor results and may damage the pump itself. Therefore, it is suggested to call up the professionals for the job. Take my words: you’ll be saved from potential hazards if you hire a professional instead of doing it yourself.
I would like to tell you about the way to heat a pool. It is simple and complex as there are few variables to consider. The simple answer is to plug and play with this basic formula from Best pool supply store phoenix.

Gallons of water (GW) multiplied by the weight per gallon (8.33lbs) multiplied by the degrees desired divided by the BTU output you have purchased for your pool.

For example, a 15,000-gallon pool heated 20 degrees with a heater output of 3,36,000 BTUs would like the following:

15,000 x 8.33= 1,24,950 lbs of water

124950 x 20= 2,499,000 BTUs need to heat the water at 20 degree

2,499,000 ÷ 3, 66,000= 6.82 hours

The variables include factors like ambient air and water temperature, wind speed, hours of sun if it is direct or in the shade, surface area exposed to the elements and your resident area location. Needless to say, if you live at the north pole and it's zero degrees outside, the pool is 40 degree in the middle of winter and there is a 10 mile an hour wind it’s going to take a long time to heat your swimming pool than it would take in the middle of summer.
